Reverb is a sound effect that simulates the acoustic reflections in a physical space. In simpler terms, it’s like an echo that is created when sound waves bounce off surfaces in a room. By adding reverb to a recording, it can create the impression that the music or vocals were recorded in a larger space than they actually were, giving the audio a more natural and spacious feel. Reverb can also add depth and texture to a recording, making it sound more immersive and engaging for the listener.
